treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

drm/xe/drm_client: Use scope-based cleanup

2025-11-19T19:58:58+00:00

Use scope-based cleanup for forcewake and runtime PM. v2: - Use xe_force_wake_release_only rather than a custom one-off class for "any engine" forcewake.

drm/xe: Return forcewake reference type from force_wake_get_any_engine()

2025-11-19T19:58:57+00:00

Adjust the signature of force_wake_get_any_engine() such that it returns a 'struct xe_force_wake_ref' rather than a boolean success/failure. Failure cases are now recognized by inspecting the hardware engine returned by reference; a NULL hwe indicates that no engine's forcewake could be obtained. These changes will make it cleaner and easier to incorporate scope-based cleanup in force_wake_get_any_engine()'s caller in a future patch.

drm/xe: Drop bo->size

2025-06-27T21:52:31+00:00

bo->size is redundant because the base GEM object already has a size field with the same value. Drop bo->size and use the base GEM object’s size instead. While at it, introduce xe_bo_size() to abstract the BO size. v2: - Fix typo in kernel doc (Ashutosh) - Fix kunit (CI) - Fix line wrap (Checkpatch) v3: - Fix sriov build (CI) v4: - Fix display build (CI) Signed-off-by: Matthew Brost Reviewed-by: Ashutosh Dixit Link: https://lore.kernel.org/r/20250625144128.2827577-1-matthew.brost@intel.com

drm/xe/client: Skip show_run_ticks if unable to read timestamp

2025-02-20T12:49:08+00:00

RING_TIMESTAMP registers are inaccessible in VF mode. Without drm-total-cycles-*, other keys provide little value. Skip all optional "run_ticks" keys in this case.
